For endogenous levels of gibberellic acid (GA3), indole-3-acetic acid (IAA) and zeatin, the extraction and purification procedures adapted were as described by Kettner and Doerffling (1995) and Pan et al.
This study aimed to evaluate the effects of different doses of ethephon or gibberellic acid on in vitro development of sugarcane seedlings.
The results showed that the fruit diameter and length, single fruit weight, endogenous hormone levels, and CsEXP 10 gene expression levels were all higher in pollinated fruits than in unpollinated ovaries, and CsEXP 10 gene expression levels were positively correlated with indole-3-acetic acid (IAA), but negatively correlated with gibberellic acid (GA3) and abscisic acid (ABA).
